Abstract

The invention relates to a device for filling containers, comprising an arrangement (7) for feeding filling material to at least one dosing system (5) forming a flow path (27) containing a dosing valve (29) that can be opened at least for the duration of the dosing processes, in order to distribute the dosing amounts of the filling material via at least one filling line (9), into relevant containers. Said device is characterised in that the dosing system (5) comprises an element (31, 33, 43) that is disposed in the flow path (27) downstream of the dosing valve (29), for selectively producing a suction effect in the flow path (27), and a control mechanism (39) that activates the element (31, 33, 43) producing the suction effect, according to dosing processes respectively completed by closing the dosing valve (29).

Description

DEVICE FOR FILLING CONTAINERS FIELD OF THE INVENTION The invention relates to a device for eaters, with a device for driving the mat at least one dosing device, q path, of flow in which a nozzle is placed which can be opened at least during operation for the dosing processes, for i amounts of the product doses through a duct filling in the containers.

BACKGROUND OF THE INVENTION The current state of the art under the re lpack® brand is known a system that makes possible an attic (molded by blow or vacuum), fill pharmaceutical products.

To comply with these requirements, in a previously mentioned type shown in document 080 Bl, for each filling duct, which is a container to be filled, a ficadora is provided, which by means of an electric drive and It closes the opening time of each dosing process in a controlled way in the ti, so that when a product is available in a distress during the opening time, the desired flow through the valve flows. dosage.

SUMMARY OF THE INVENTION devising the state of the art the invention is the task of presenting a device of the type At the end of the dosing process, one of the metering valves in the flow path produces a traction effect on the dosing process in the duct, resulting in a suction effect, which allows an excess of the remaining liquid in the duct of fillers prevents the dripping of the liquid. In any case, one. high accuracy in the dosage.

In the case of exemplary embodiments, the metering valve is seen and the re-entry conduit presents a throttle position, the area of the throttle position, a function which, depending on its positioning, defines the flow path, which upon activating the The traction effect can be carried out in the flow direction or in the position of the ul derivation of the choke position, co b has one. application of the volume of the trajectory and with this a flow effect is obtained.

Advantageously, the device that produces the tensioning effect before a bypass valve of the shape of an embrana, whose membrane forming the limb 1 limits with its closing side the thrusting thrust path and in whose other role can be applied a sub-pressure for traction, to allow the membrane deviation that broadens the trajectory, d movement, produces the effect of traction in the I filling. In this case of examples of embodiment, the device producing the effect of a construction is substantially simple. of the flow path.

To support the movement of the metering valve membrane as well. in the vavation to the rest position, this corresponds to the closing position, and deflection pro- ductions from the control repos position of the diaphragm opposite to the dosing valve side and in the valve of flow through control ducts excessively pressure as suction pressure as opening pressure.

Here, advantageously, it can be considered that a plurality of dosing flow lines assigned thereto are intended to be dosing, where the sides of dosing channels in question are connected. a joint control duct, while s of membrane control in the valves dosi each filling duct are provided with separate rollers for pressure and suction.

BRIEF DESCRIPTION OF THE FIGURES Next, the invention will be described with the help of representation represented individually, in which: FIG. 1 shows a side view, partially in the middle of the scale, of a practical embodiment of the spontaneous dosing block distributing the product of an embodiment of the device according to the invention.

Figure 2 shows an enlarged rada representation compared to the f illustrate the way of construction and operation of the metering valve according to ?? of carrying out the invention.

DETAILED DESCRIPTION OF THE INVENTION ntinuation is described. the invention with the aid, in which the device has a plurality of dosing devices, mainly to the representation of the fifteen dosing devices, which are greased in a common dosing block 1.

The product distributor 3, in which the product is to be introduced, is under a predetermined factor, each of the devices 5 inside the dosage unit 1 of the filling product through a In such a device, a production unit is shown in FIG. 3. As seen from this figure, each osi-tives has a filler pin 1, which in the figure above is provided with a feeder head 13 for feeding the filler pin 11 with means. FIG. 3 shows a duct 9 with a channel of the product 1 centrally in the filling pin 11 in the feeder head 11. The liquid is dosed through the condiments 9 at the needle-like end 17 of the needle 9. * filling spigot 11 to fill one of the 19 in questioners, which in a device according to the aforementioned bottelpack system From one of those devices in the fi The filling tubes 9 in question come out in the needle-like form 17 of the filling pin in one of the containers 19 in question, which has a molding device 21 according to the aforementioned elpack®, from a handle 23 that is produced from a material by means of an extruder head 25.

Other features of the grinders 5 combined in the dosing block are shown in FIGS. 2 and 5. As flow observation 27 extending between the assembly 7 and the filling conduit 9 is essentially two valves, in fact a grinder 29 upstream and a bypass branch placed downstream 3 ulas are membrane valves with a mem FIG. 29 presents a pneumatic connection 3 for the individual application on the control side of the pressure or suction dosing device 29. In 1, all of the pneumatic bypass connections 31 are numbered, they all have a joint attic 39 for applying pressure or suction ontrol 37 of the membrane 33 in the valve of question.

The operation of the devices 5 is better seen in FIGS. 4a to Fig. 29 on the metering valve 29 and on the side 31 on the control side 37 of the membrane enters a zone 43 in the form of a spherical cap inside. of the flat area can be deformed 33, when applied from the ion control side through pneumatic connections with the in the closed position, while the f time shows the metering valve 29 bypass valve 31 open. In the valve of the flow path 27, a post-angulation 41 is found. FIG. 4a shows the device position before a dosing process, the dosing valve 29 is still closed, the bypass valve 31 is located in the rta. In this open position of the valve of d in which the membrane 33 is deformed from the space in the form of a spherical cap and flow axis 27 in front of the state in the closed bypass casing 31 is found to correspond to the volume of the cion. In the case of a bypass valve, the flow rate is not only available that dosing by closing the pill 29 (Figure 4c). At the end of closing the tapper 29 the bypass valve 31 spontaneously to FIG. 4d. The deformation run of the membrane 33 in the spherical cap a is 42 leads to a trial of the flow path 27 of the vagina 31. This reciprocating movement of the closed siphon metering valve 29 before the suction , by means of which a liquid of the subsequent filling conduit 9 is presented.

As already mentioned, the dosed determination is carried out by means of the control of the opening duration of the dosed valve through the pneumatic connection, individualization of the suction effect in the air ducts. trajectory of the flow not strangulated 27 for cleaning and sterilization, this is the distribution of the product 3 from condition 7, the dosing device 5, the coelin 9 to the channel for the product 15 of u elleno 11 in question.
